HEINRICH ZOELLY, OF ZURICH, SIVITZERLAND.

TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 452,590, dated May 19, 1891.

Application filed January 15, 1891. Serial No. 377,821 (No model.)

To all whom, it may concern.-

at the rim, so that the downward water-press- Beit known that I, HEINRICH ZOELLY, a citiure at both sides of the opening at the rim zen of the Republic of Switzerland, residing at Zurich, in Switzerland, have invented certain new and useful Improvements in Tur bines, of which the following is a specification.

The object of my invention is to provide certain new and useful improvements in vertical shaft turbine water-wheels for the purpose of counteracting the vertical pressure of the shaft on the step or for removing said vertical pressure entirely orpartially.

The invention consists in the combination, with a casing, of the vertical shaft, upper and lower turbine water-wheels on said shaft, the upper turbine wheel having a disk extending from the hub to the rim for receiving the upward pressure of the water to counteract the downward pressure of the shaft on the step, and a guidewheel for the lower turbine wheel, having all parts closed from the hub to the run.

The invention also consists in the construction and combination of parts, as willbefully described hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical transverse sectional view of my improved turbine water-wheel in a plane parallel with the axis of the inlet-opening. Fig. 2 is a similar view at right angles to the plane of the axis of the inlet-opening. Fig. 3 is a horizontal sectional view on the line A B of Fig. 1. Fig. 4: is a similar view on the line C D, Fig. 1; and Fig. 5is a vertical transverse sectional view showing a modification.

Similar letters of reference indicate corresponding parts.

The shed or casing a of the turbine waterwheel is provided with the fixed guide-wheels 0' c concentric with the vertical shaft 1), which shaft is tubular and is supported by the interior shaft d, resting on the step a in the cross-bar a of the bottom outlet-tube a, supporting the casing a. The driven shaft 1) is connected with the upper end of the shaft 1) in any well known manner. The lower guide-wheel a is provided with a closed hood 6, forming a guide for the shaft 12, which hood 6 covers those parts of the wheel 0 between the hub and the openings f connects the rim-pockets with the hub.

The upward pressure of the water on said disk f counteracts the downward pressure of the shaft on the step and takes up the same partially or entirely. The lower turbine-wheel is constructed in the usual manner and receives no downward pressure, except that acting on the pockets or openings of the rim. On the top of the casing an annular hood G is provided for receiving the water passing up through the upper wheels f" and 0 which water passes from said hood throu gh thej acket h around the casings a in the outlet-tube a. If desired, said hood g and jacket h may be dispensed with and a U-shaped tube g arranged on the top of the casing A, as shown in Fig. 5, which U-shaped tube g is connected with a second outlet-pipe 7t for the water passing through the upper wheels. It is also advisable to make the upper wheels largerin area than the lower ones, so as to utilize the upward pressure on said wheels in conjunction with the pressure on the disk f ,for taking up the downward pressure on the step.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
